--------------------------------------------
Thanks for the confirmation!
> GridPager links need to send page's request parameters
> ------------------------------------------------------
>
> Key: TAP5-1358
> URL: https://issues.apache.org/jira/browse/TAP5-1358
> Project: Tapestry 5
> Issue Type: Improvement
> Components: tapestry-core
> Affects Versions: 5.1.0.5
> Reporter: Geoff Callender
> Labels: bulk-close-candidate
>
> GridPager uses EventLinks, but EventLink has a problem: even though it DOES
> send the page's activation context (which is good), it DOESN'T send the
> page's request parameters (which is bad)!
> Does this happen in 5.2 too?
> This is a real problem since I like to put search/filter criteria into
> request parameters and not the context. The problem is that when I click on a
> GridPager link I lose the search/filter criteria. Why do I use request
> parameters for search/filter criteria? Because it is arguably more RESTful.

> Example
> A page has enterable search criteria fields (name, department, status).
> Type in a name and submit the page. We redisplay with the Grid populated and
> more than one grid page.
> If the page puts the search criteria in the activation context then the
> GridPager's link to page 2 looks fine - like this...
> http://localhost/myapp/things/index.grid.pager/2?t:ac=jack/$N/ACTIVE
> ...however if the page puts the search criteria in the request parameters,
> then the GridPager's link to page 2 looks inadequate - like this...
> https://localhost/myapp/things/index.grid.pager/2
> ...but to prevent losing the request parameters it should be like this...
>
> https://localhost/myapp/things/index.grid.pager/2?name=jack&status=ACTIVE
> I wasted a lot of time figuring out this was what was going wrong, even
> though I could see this what was happening, because I was refusing to believe
> that request parameters weren't getting equal treatment in this situation!
